"Thou we are not now that strength which in old days moved earth and heaven that which we are, we are.One equal temper of heroic hearts made weak by time and fate but strong in will to strive, to seek, to find and not to yield"

That thing is going to wake up one day and the world will never be the same.

"God forbid we should ever be 20 years without such a rebellion. The people cannot be all, & always, well informed... If they remain quiet under such misconceptions it is a lethargy, the forerunner of death to the public liberty... Let them take arms... What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots & tyrants. " - Thomas Jefferson in 1787

well, I don't think it would work to well in the atmosphere...does not even resemble what I would think would be a communications or spy satellite...my guess is a time ship or intergalactic scout ship...

The "Black Knight" sat has been known about and up there for many years!

There are two basic choices.

a.) it's been orbiting since pre-deluvian times and is a product of a much earlier and much more advanced civilization that was flourishing on this earth sometime before 3000 BC.

b.) it was placed there by some other alien civilization perhaps to monitor radio and electro-magnetic transmissions from earth - relaying them to some distant civilization that may or may not still be in existence today.

We now know that Faster-than-light travel is entirely possible, chances are extremely high that transmission of information using entangled objects is also possible and can take place instantly across vast reaches of space and even perhaps across time.

This could also be some sort of defensive device placed in orbit by either a benevolent alien civilization or a pre-flood ultra-advanced civilization that was thriving on earth in the distant reaches of prehistory, that can and will be called upon to deflect potential collisions with comets, asteroids, etc. If that is indeed what it is - we can only hope it is still working should it ever be needed before our own tech can provide a similar level of defense against such potential world-destroying entities.
